Now a new study has found that sniffer dogs' abilities extend to reliably detecting lung cancer. The researchers say the results of the study confirm that there is a stable marker for lung cancer, which offers the possibility that a "breath test" for the early detection of lung cancer could be developed.Link to Original Source
